You learn the set-down transfer in week one: wrap tight, move slow, hold your breath. A bigger blanket forgives the wobble.Smiling sharks and little fish — the friendly version of the shark phase.It measures 47 by 47 inches — the size that actually holds. Hospital-issue swaddles run about 44 inches square — and those missing inches are why the wrap that held at 8 p.m. is loose by 3 a.m. Three extra inches reads like a rounding error — until week three, when it's the difference between rewrapping and sleeping.Material. Tanboocel® Bamboo Viscose, blended with cotton and woven into open-weave muslin. Tanboocel® is a branded bamboo viscose made through a closed-loop process — third-party verified, with a lower water and chemical footprint than the generic bamboo rayon most brands quietly label "bamboo." It gets softer after the fifth wash than on day one, the opposite of how cotton ages.The print. Cream-ivory ground (navy binding) with watercolor smiling sharks — great white, whale, hammerhead, and tiger — in white, gray, and blue tones, with small fish and blue stars.One blanket, many jobs. The newborn swaddle is the first use. The swaddle phase runs 8 to 16 weeks for most babies; the blanket keeps working long after — stroller shade, nursing cover, tummy-time mat, light summer layer. It outlasts the swaddle window by years.When to stop swaddling. The arms-in swaddle ends the moment the baby shows signs of rolling — usually 8–16 weeks. The AAP guidance is firm on this. Past that point, switch to a 0.5 TOG muslin sleep bag (warm nursery) or a 1.0 TOG TENCEL™ sleep bag (everyday nursery) with arms free.Adjacent products. Once the swaddle phase ends, the natural next step is a 0.5 TOG Muslin Sleep Bag for warm nurseries or a 1.0 TOG TENCEL™ Sleep Bag for the everyday 69–75°F room.Care. Machine wash cold and tumble dry low. Tanboocel® takes the dryer better than bamboo rayon, with less pilling and shrinkage over time. Don't bleach; iron on low only if you need to.Safety & certification. AAP safe-sleep compliant and tested to CPSC, CPSIA, and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation. Common questions When should I stop swaddling my baby? Stop the arms-in swaddle the moment the baby shows signs of rolling — usually 8–16 weeks. After that, switch to a 0.5 or 1.0 TOG sleep bag with arms free. The AAP's guidance is firm on this: a swaddled baby who rolls onto their stomach is at meaningfully higher risk. What size swaddle blanket is best? 47x47 inches is the size that holds together. At roughly 44x44, hospital swaddles run small; the loosening you notice at 3 a.m. starts there. The three-inch difference matters more than it sounds like it should. Can I use a muslin swaddle as a nursing cover? Yes. It moonlights as a nursing cover, shades the stroller, pads tummy time, and finishes as the summer blanket. Open-weave muslin breathes well enough that you're not creating a hot pocket while feeding. Browse all baby swaddle blankets.Free US shipping over $65.
